Abstract
Description
- The present invention relates to packaging machines and more particularly to a film drive unit of a packaging machine.
- In the packaging of products which comprises a plurality of discrete units, it is common for a tubular bag material to be formed from sheet material, the tubular bag material is delivered to a filling head whereat the product is delivered to the interior of the tube material. The tube material is subsequently sealed at spaced intervals and discrete bags severed from the tubular material. The sheet material generally comprises a plastic film which is sealed by heat or other means to form the tubular material. The plastic film is joined along its longitudinal edges to form the tubular material. Generally the film is drawn through the packaging machine by means of vacuum belts or alternatively the sealing head frictionally engages the tube material in order to advance the tubular material through the packaging machine.
- Packaging apparatuses which employ belts to pull the bag material through the apparatus are described in US Patents 4,501,109; 3,844,090; 4,128,985; 4,423,585; 4,288,965 and 4,663,917. In these US patents, the belts frictionally engage the bag material, which frictional contact is sometimes enhanced by applying a vacuum to the rear side of the belt.
- US Patents 4,524,567 and 3,850,780 describe rotary sealing jaws, which frictionally engage the bag material to draw the bag material through the packaging apparatus.
- In many machines rollers are employed to advance the packaging material through the apparatus. For example, in US Patent 3,916,598, rollers pull the bag material over a former.
- In the above discussed US patents, where rollers are employed, no means of enhancing frictional contact with the bag material is provided while still further, the rollers are not used to longitudinally seal the bag material.
- The above discussed methods of moving the tubular bag material through the packaging machine are generally complex and therefore costly to manufacture. Additionally their complexity adds to the maintenance required.
- Swiss specification 602460 (UK Patent 1577882) describes a vacuum roller. The vacuum roller consists of an outer cylindrical member which is caused to rotate. Located within the cylindrical member is a plenum member to which a vacuum is delivered. The outer cylindrical member is provided with radially extending passages which selectively communicate with a chamber formed in the plenum member. In this particular device, the internal plenum member has no means for adjusting either to the irregularities of the outer cylindrical member or for wear of the plenum member and cylindrical member. In high speed packaging machinery, this particular vacuum roller would rapidly fail due to these inadequacies.
- It is the object of the present invention to overcome or substantially ameliorate the above disadvantages.
- There is disclosed herein a driven roller, for a film drive unit, to frictionally engage and move sheet material in a packaging machine upon operation of said driven roller, said driven roller comprising:
a hollow cylindrical driven member having a cylindrical outer surface to engage said material and a cylindrical inner surface, said cylindrical member having a plurality of apertures extending between said inner and outer surfaces; and
a stationary plenum member within said cylindrical member and about which said cylindrical member rotates, said plenum member including a base portion and a movable vacuum transfer portion supported by said base portion and engaging said inner surface, means urging said transfer portion towards said inner surface, said base portion and said vacuum transfer portion co-operating to provide a plenum chamber, a duct means in fluid communication with said plenum chamber to deliver a vacuum thereto to generate a negative pressure in said plenum chamber, and at least one vacuum cavity, formed in said vacuum transfer portion, extending peripherally along said inner cylindrical surface so as to be radially aligned with said apertures as they pass said cavity, said vacuum cavity is in fluid communication with said plenum chamber so that a negative pressure can be formed at said apertures so as to draw said material into contact with said outer cylindrical surface. - A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings, wherein:
- Figure 1 is a schematic perspective view of a film drive unit for a packaging machine;
- Figure 2 is a schematic side elevation of a portion of the drive unit of Figure 1;
- Figure 3 is a schematic side elevation of the drive unit of Figure 1 incorporated in a packaging machine;
- Figure 4 is a schematic end elevation of the packaging machine of Figure 3;
- Figure 5 is a schematic part sectioned end elevation of a roller employed in the drive unit of Figure 1; and
- Figure 6 is a schematic sectioned side elevation of the roller of Figure 5 sectioned along the line A-A.
- In the accompanying drawings there is schematically depicted a film drive unit 10 of a packaging machine 11. The packaging machine 11 has a
shaft 12 which receives aroll 13 of plastic film which is in strip form. Thefilm 14 is delivered in a conventional manner to a former 15 which wraps thefilm 14 about a longitudinal axis so as to formtubular bag material 16. The tubular bag material is moved by means of a pair ofrollers - Located above the former 15 is a
delivery hopper 19 having a lower end through which the material to be packaged is delivered into thetubular bag material 16. Thetubular bag material 16, after passing therollers assembly 20 which forms discrete bags. For example, theassembly 20 could be the stripping and sealing assembly disclosed in Australian Patent Application No. 43753/85. - The
rollers rollers supports linkages joint 25 so that therollers rollers supports - Extending downwardly from within the former 15 is a
back seal bar 26 which co-operates with theroller 18 to join the longitudinal edge portions of thefilm strip 14 to form thetubular material 16. In this particular embodiment, the longitudinal edge portions are heat sealed. - In Figures 5 and 6 the
roller 18 is more fully depicted. As described previously, theroller 18 is rotatably mounted on asupport 22 which is a driven tubular member supported at its extremity by means of abearing 27 mounted on aspigot 28. Extending radially from thesupport 22 is aflange 29 which supports acylindrical member 30 which receives a high friction material 31 (or surface finish for example silicon rubber) to aid in gripping thetubular plastics material 16. Anend plate 32 is attached to thespigot 28 by means of threadedfasteners 33 engaging aplenum member 35 mounted on thespigot 28. Theplenum member 35 is provided withplenum wear pads 34 which engage theinner surface 36 of thecylindrical member 30. Thespigot 28 is tubular, so as to provide passage 60, and is connected to plenum chamber 56. Extending from plenum chamber 56 arepassages 37 which communicate withplenum cavities 38 aligned with rows ofapertures 39 extending through thecylindrical member 30 and thefriction material 31 mounted thereon. Thecavities 38 extend about theaxis 40 of theroller 18 peripherally over an arc so as to communicate with theapertures 39 during a predetermined angular displacement about theaxis 40. - The
plenum member 35 provides a plenum base portion in the form of aflange 43 having an internal cylindrical surface 44 including the plenum chamber 56 which slidably receives apiston 45 biased outwardly by means of a pair ofsprings 48 wound aroundguide pins 53. Theguide pins 53 are slidably received withincavities 54 formed in thepiston 45. Asealing ring 55 sealingly connects thepiston 45 and the internal cylindrical surface 44 of theflange 43 so that a vacuum delivered to the plenum chamber 56 is contained and delivered to the outer surface of theroller 18 viapassages 37 extending to theplenum cavities 38. The outer peripheral surfaces of thepiston 45 are provided with theplenum wear pads 34. - A heater assembly 41 is also mounted on the
spigot 28. The heater assembly 41 includes abase 42 which is semi-circular in configuration and has an angularperipheral surface 46 which engages theinner surface 36 of thecylindrical member 30 so as to transfer heat to theannular projection 47 of thecylindrical member 30. Thebase 42 is pivotally mounted by means of apin 57, and is biased outward into contact with thesurface 36 by means of aspring 58 wound around aguide pin 61 slidably received within thebase 42. Thebase 42 is also provided with aheater element 49 which receives an electric current. - In the present embodiment, only the
roller 18 is provided with a heater assembly 41. This requires thepiston 45 to have anarcuate slot 59 through which theangular portion 62 of thebase 42 passes. - In operation of the heater assembly 41, the
projection 47 engages the bag material to cause fusion thereof by heating the bag material. - The
roller 17 is of a similar configuration to theroller 18 however no heater assembly 41 is provided. However theroller 17 is rotatably driven and is provided withapertures 39 selectively communicating with a plenum in a similar manner to theroller 18. - It should be appreciated that the
plenum cavities 38 of theroller 18, and the similar plenum cavities within theroller 17, are located so as to be adjacent thetubular material 16 so as to draw thetubular material 16 into frictional contact with the outer surfaces of therollers spigot 28. Since both thesupports tubular material 16 is drawn from theroll 13 of the former 15 to be delivered to theassembly 20. - In Figure 2 the lower extremity of the
back seal bar 26 is more fully shown. Theback seal bar 26 is provided at its lower end with acarriage 50 supporting tworollers tubular bag material 16 into contact with the heatedannular flange 47 of theroller 18 so as to seal thelongitudinal edges 53, of thetubular bag material 16 together. - If so required, neither of the
